This doesn't affect anything I do, but I just noticed an anomaly in the figure shown for number of consecutive days solving puzzles. If I go into my history, it shows 532 consecutive days. However, I have only been a member of the site for 497 days.

Yeah, my number dropped too. But, I think I really did miss a day - I just got credit for the timed puzzles that day from the prior day. I'm guessing it was previously counting for the later day but is now being counted with the prior day when the timed puzzles were actually completed.
